AWS Rekognition Faces Comparison response metadata analyses

Dear Experts, I would like to ask whether you have an idea how I could go deeper in my AWS Rekognition Face Comparison response metadata analyses. I have a set of pictures that are validated between each other, yes I am satisfied how well the tool actually works, but I would like to go dive deeper in the response metadata. Some of my face comparisons do result in false negatives and for those I would like to know why the pictures resulted in a mismatch. The response does give the confidences for certain facial attributes, but to me if the LEFT EYE: X = 0.23131 and Y = 0,3221 is in these coordinates and other is mismatched with relatively similar coordinates then that doesnt really tell me much. My question is whether there is a way to visualize what the Face Comparison tool highlights as similar and what it doesnt, it could be a heatmap of the face or some other.
